In this four-part series produced contemporaneously with Werner Herzog’s documentary “Into the Abyss,” the internationally renowned filmmaker embarks on a dialogue with death-row prisoners and lets them express their views on life and death. Four men and one woman locked up in a Texan prison for murder and other crimes. As Herzog looks deep into these individuals, their stories, and their crimes, his penetrating journey into the human soul also becomes a plea for humanity and understanding.
